optional parts for 1/12 scale ?

i was just looking at those Fujimi 1/12 scale R32 GTR kits and they seem like a whole lotta fun to build ! and so much room for awesome detail !!! however, its BONE stock and thats really no fun... so i was wondering if any aftermarket parts were available for that kit... i know that i can purchase the NISMO version and get some side skirts etc... but im actually lookin for bigger aftermarket wheels, racing seats, brakes etc... thanks

The only after market stuff I've seen for 1/12th scale kits are for formula ones. I have yet to see anything made for regular 1/12th scale "car" kits.
